Bars, Plates, Seamless tubes | Alloyed boilersteel, Stainless, acid & heat resistant steel | Plate: A/SA 387 gr 91. Round steel: A/SA 182 F91. Pipe: A/SA 335 P91 | 1.4903 | 650°C |
X10CrMoVNb9-1, also known as 1.4903 is an alloy martensitic pressure vessel steel. The material is designed to be a heat-resistant steel that provides high creep resistance. The steel also has an increased impact strength.
The low carbon content gives the steel properties that are particularly suitable for both mechanical processing and welding. 1.4903 is a material used in applications where conventional heat-resistant steels cannot meet the requirements.
This type of steel is often used in high temperature applications such as power plants, chemical plants and oil refineries due to its excellent resistance to oxidation, creep and high temperature strength.
Overall, steel 1.4903 is a high performance material well suited for use in extreme temperature and pressure environments.
